Filed: 1987-06-04
Abstract: PURPOSE:To obtain a highly reliable servo circuit by providing an A/D converter which makes a difference signal be an analog input, and besides, makes a sum signal be a reference input, and outputs the digital signal of an offset binary type, as a normalization processing means. CONSTITUTION:It is assumed that the outputs of IV converters 2, 3 are positive, and an output offset reference value V0>0. The sum signal Vx=x+V0 and the difference signal Vy=y+V0 of operational amplifiers 4, 5 are obtained, and the A/D converter 17 compares between the signal x+V0 and + or -y+V0 by a width, corresponding to its bits number and encodes them. An output signal DB comes to be a full code in a condition that a light spot concentrates to a detector 1a (x=y), and comes to be a zero code if a light receiving quantity is zero (x=-y), and it comes to be code information that the value (x) is normalized by (y). Besides, because if x=0, the code information in the signal DB has the offset of 1/2 full code, it comes to the offset binary type. When a D/A converter 19 performs a focusing drive 8 so that an operating point comes to zero by outputting the signal Ax, and performs a tracking drive 15 by the signal Az, it can servo-control a device at a high reliability.

Title: Beam expander and optical head using the same
Inventor: TANAKA YASUHIRO
IPC: G02B27/00
Filed: 1991-06-11
Abstract: PURPOSE:To expand the beam diameter of parallel light by an afocal optical system which has short overall lens length while holding the light parallel by setting a specific condition for the overall length of the afocal optical system, the expansion rate of the diameter of the beam, and the diameter of the projection beam. CONSTITUTION:In the afocal optical system which expands the parallel incident beam and emits the parallel light, a 1st lens with negative power and a 2nd lens with positive power is arranged from the incidence side. When the incident beam is transmitted through the 1st lens having an aspherical surface and the 2nd lens, the condition shown by an inequality is satisfied. In the inequality, L is the overall length of the lens, D is the emitting beam diameter, and (m) is the expansion rate. This constitution corrects a spherical aberration and a sine condition even when the overall lens length is shortened to hold a wave front aberration within a diffraction limit. Consequently, the compact, high- performance beam expander which consists of one or two lenses and has short overall lens length is obtained.

IPC: H01L21/18
Filed: 1986-06-17
Abstract: PURPOSE:To prevent the generation of voids on a directly adhered wafer by a method wherein at least a penetrated hole is provided on one of two semiconductor substrates. CONSTITUTION:Each of two mirror surfaces are adhered without interposing the foreign matter such as air and the like between them using two mirror- polished semiconductor substrates, one of which has a penetrated hole, and a heat treatment is performed.

Title: Control tone transmission system ion fm radio system
Inventor: YUMIBA MASAHIRO
IPC: H04L27/32
Filed: 1991-06-12
Abstract: PURPOSE:To allow separate demodulation circuits to extract a demodulated audio signal and a control tone respectively by applying AM modulation to a carrier subject to FM modulation by the audio signal through the use of the control tone. CONSTITUTION:An AM modulation circuit 1 for control tone signal modulation is added to the system. The AM modulation circuit 1 implements AM modulation by using the control tone signal to AM-modulate a power supply for a power amplifier section 13 of an FM transmitter to change a level of a carrier signal subject to FM modulation. On the other hand, an amplitude limiter of an FM demodulation circuit in an FM receiver excludes an AM component. Furthermore, a discriminator demodulates the FM-modulated audio signal to obtain an audio output component, and an AM detector applies envelope detection to the output of a 2nd intermediate frequency to obtain a voltage change for the AM component. Then a tone detector detects a control tone components from the voltage change obtained from the AM detector, then the detector rectifies the component and the result is fed to a comparator circuit, in which a desired control output is selected and extracted.

The signal read out from memory 15 is branched with the polarity inverted by inverter 18. Then switch 19 is switched every sample value, and then the sample is drawn out one by one and alternately from the signal just read out from memory 15 and its reversed signal. The luminance signal component is eliminated from the output through LPF20 to obtain the color signal. However, for the output of the LPF, only one kind of color signal is obtained alternately and with every 2nd line. In this connection, the interpolation is carried out through the circuit comprising 1-line delay lie 21 plus switches 22 and 23, thus drawing out the continuous two color signal through signal output terminals 24 and 25.
